SPECIFICATION forming part of Letters Patent No. 752,906, dated-February23, 1904.

' Application l'lled March 21, 1903,

To all w/wm 5 may concern:

Beit known that I, JAMES W. KELLY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented a new and usefulr Improvement in Water-Closets, `of which thefollowing is a specification.

My invention relates particularly to selfiiushing water-closets; and myprimary object is to provide a closet of this character of improvedgeneral construction, particular attention being paid to securingsimplicity of structure, certainty of operation, freedom from danger offreezing, and freedom from liability to get out of repair. In thisconstruction the tank is located beneath `the lloor-line and suitablydrained to prevent freezing. W'hen the seat of the closet is depressed,'water is admitted to the tank, compressing the air therein, and whenVthe pressure upon theseat is removed the air furnishes the pressure forflushing the closet.

The invention is illustrated in its preferred embodiment intheaccompanying drawings, in whichy Figure 1 represent-sa side 'view' ofthe closet; and Fig. 2, a broken vertical sectional view of the tank,Hush-pipe, and valve mechanism.

A description of the preferred construction follows. A

' A represents a closet-bowl provided at its rear upper portion withv acombination pipe connection and bracket A; A2, a soil-pipe or soil-pipeconnection provided at its lower end with a trap A3; B,'a tank locatedbeneath the lloor B; B2, a Hush-pipe extending throughthe tank andjoined ,at its upper end to the connection A; B3, a connection at thelower end of the tank, forming virtually an eXtension of the pipe B2;B4, a water-supply pipe communicating with the connection B3; B5, adrain-pipe connecting the member B3 and the portion with valves C, C2,and C3 and having a projecting upper end equipped with a head C4,Vbetween which and the connection is confined la spring C5, and D a seathaving its frontportion resting normally onf the front portion ofthebowl and'provided at its rear portion with a lhinge D', one leaf ofwhich Serial No. 148,855. (No medal.)

bears upon the upper I' end :of fthe valve-stem or plunger-rod and hasits rear end joined by,

a pivote to the member A. I Y

The bowl A may be of any suitableconstruction. The connection A isreally a T- shaped, pipe-section, with a bracket on the outer side ofthevertical portion or cross of the T. The vertical channel of the T iscapped by a suitable perforated cap or gland e, through which 4thevalve-stem passes. The tank B is provided at its upper end with acentral opening for the pipe B2, the latter being externally threadedadjacent-to' theopening to receive a nut 5. The pipe B2] is providednear 'its lower end withV perforations 5", communicating with the tank,and at a short distance above the same with two series of perforations52 53, separated by an imperforate portion 54.v The perforationsZ22-communicate with the perforations 53 through an annular ,passage orby-pass 55, formed by an enlargement 55 on the pipe.y The member B3comprises a tubular member 57, flanged at its 1 upper end and havingliquid-tight connection f thereat with the lower Vend of 'the tank B, an

externally-threaded nipple 58 at one side there- `of for attachment withthe pipe Bi, a longitudinal enlargement?) having a channel 51, fconstituting a ley-pass from thev tank to the lower Vend of the tubularportion, andY a bottom cap 5u, having an externally -threaded stemconnected with the pipe B5. 'Ihe member B3 has its upper end enlarged atits inner diameter and threaded thereat to receive the lower end of thepipe B2.' Gaskets 512.513 serve to make liquid-tight joints, the tankbeing, as it were, clamped between the nut 5 and the flange of themember Bi. f Y

The valve-stem C is preferably constructed of thread-connected sectionsfor convenience in applying the valves. Near the upper end is a collarc, which normally bears against a gasket c at'the under side of thegland c. The inner diameters of the pipe B2 and member B3 are equal, asare the diameters of all the valves. In the normal position of thecloset the valves are located 'as Aindicated in f IOO the valve-stem isdepressed the valves occupy the position indicated by the dotted lines,in which position communication with the bowl is cut off andcommunication between the admission-pipe and tank established.

The seat serves to depress the valves to per-l mit the tank to receive acharge of water and the airin the tank to become compressed by thepressure from the hydrant. When the seat is relieved of its pressure,the valves are raised by the spring C5, disconnecting the tank from thehydrant, establishing connection between the tank and bow-l, andreopening the drain-passage 61, the lower end of which has in themeantime been closed by the valve C. The height to which the tank willbecome lled will of course depend upon the pressure at the hydrant. Thedotted line d represents the water-level under a certain pressure. Afterthe tank has become so nearly empty that the air-pressure no longer willserve to force the water through the bowl the tank and the pipe B2 willdrain through the pipe B5.

In addition to its function in depressing the valve-stem the hinge Dpermits the seat to be thrown back, swinging upon the pintle of thehinge to the inclined position indicated by dotted lines, in whichposition it is free from danger of falling. An advantage incident to theconstruction is that the bowl may be placed close to a wall, and,moreover, it is unnecessary to inclose the front portion of the bowOther advantages incident to the general construction will readilyappear to those skilled in the art. For instance, the feature oflocating the valves within the pipe B2 obviates the necessity of havinga pit for a valve located outside. When the valves are in the positionindicated by the full lines, the pressure upon the lower surface of thevalve C2 is balanced by the pressure on the upper surface of valve C',and when the valves'are in the position indicated by dotted lines thesame thing is true, and in addition to this the pressure upon the uppersurface of the valve C2 is balanced by the pressure upon the lowersurface of the valve C3. The valves are perfectly balanced, therefore,so that the valve-stem is readily depressed and is readily raised by thespring C5. The valves may be removed for repair by unscrewing the glanda and withdrawing the valve-stem from above. Other advantages appertainto the construction, which will be understood by those skilled in theart.

It readily will be understood that changes in details of constructionwithin the spirit of my invention may be made. Hence no undue limitationis to be understood from the foregoing detailed description,the samehaving been given for clearness of understanding on y.
